JPYSC Overview
JPYSC (JPYSC) is tracked under jpysc. The local profile associates it with Stablecoins, Ethereum Ecosystem, JPY Stablecoin. The source profile maps it to ethereum.
Asset Role and Supply
Its role should be evaluated through network or product use, supply design, governance, liquidity, and trading-venue quality. The reviewed record shows circulating supply about 20.03 billion JPYSC, total supply about 20.03 billion JPYSC. Supply fields may change through issuance, burns, migrations, or source revisions and should be checked against project records.
Market Structure
At the 2026-09-12 review, the local snapshot placed JPYSC at market-cap rank #231, with market capitalization about $130.45 million and reported 24-hour volume of $0.00. These values describe observed scale and turnover, not fair value or guaranteed executable liquidity.
YearBull Perspective
The dated snapshot recorded YearBull Rank #2,571, Bull Score 46/100, Risk Low, and Cycle Early. Rank, Bull, Risk, and Cycle answer different questions and should be read together.
Key Risks
Material risks include market volatility, liquidity deterioration, protocol or governance failure, concentration, and regulatory change. Historical prices, rankings, and classifications do not predict future performance. Verify contract addresses, network support, custody, and venue availability before acting.

JPYSC: How SBI’s Trust-Based Yen Stablecoin Works
JPYSC is a Japanese yen-denominated electronic payment instrument issued through a trust structure involving SBI Shinsei Trust Bank, distributed by SBI VC Trade, and deployed as an Ethereum token. Its design combines segregated trust assets with controlled access to issuance and redemption, but public-chain circulation remains limited at launch.
A trust-based claim on yen-linked assets
JPYSC is structured as a yen-denominated specific trust beneficiary right rather than as a conventional unsecured token issued by a software company. SBI Shinsei Trust Bank acts as trustee, while SBI VC Trade is the settlor and initial beneficiary. The trust assets are managed separately from the trustee’s own property and consist of bank deposits and Japanese government bonds. The issuer describes the token as designed for a one-to-one exchange relationship with the Japanese yen, but also discloses that changes in Japanese government bond market values could create a shortfall against the token’s principal. JPYSC does not pay interest or distribute the income generated by the trust assets.
Who issues, distributes, and redeems JPYSC
The system separates the legal issuer from the customer-facing distribution channel. SBI Shinsei Trust Bank issues JPYSC on the blockchain after receiving the relevant trust funding, while SBI VC Trade provides the purchase and buyback interface. Customers purchase through an SBI VC Trade account and receive yen when they submit JPYSC for buyback, subject to account, identity-verification, banking, and compliance procedures. Holders can also seek direct redemption from SBI Shinsei Trust Bank, although that route requires a formal application, wallet information, legal checks, bank-account details, and a redemption fee of 3,000 yen per application before tax, in addition to applicable transfer costs.
Ethereum deployment does not yet mean open access
The JPYSC contract is deployed on Ethereum at 0x6781d5631BFe47432b089e64e3EaB3b6eDd26177. Etherscan identifies the address as a proxy contract and records an implementation address and a proxy upgrade event, so the deployed address should be treated as an upgradeable software component rather than as immutable code. The practical meaning of that deployment is narrower than the existence of an on-chain contract might suggest. SBI VC Trade states that JPYSC deposits and withdrawals are not currently supported, and that public-chain circulation is intended to expand only after the relevant legal, tax, and supervisory treatment has been clarified. At launch, users therefore interact primarily with a regulated intermediary account system rather than with an unrestricted Ethereum settlement asset.
The token’s intended users and use cases
JPYSC is aimed less at anonymous retail payments than at regulated yen settlement, treasury movement, and transfers connected to digital assets. SBI and Startale’s project materials describe intended applications including enterprise settlement, cross-border financial connectivity, onchain payments, and settlement for tokenized assets. Those statements are project objectives rather than evidence that each use case is already operating at scale. The current SBI VC Trade service offers account-based purchase at one yen per JPYSC, with Ethereum listed as the supported network, but the exchange’s own disclosures make clear that several blockchain-based benefits are prospective until external transfers become available.
Control is institutional, not token-governed
The available project materials do not describe a public governance token, DAO, or holder voting process for JPYSC. Operational control is instead distributed among the trustee, the distribution provider, and the technical system supporting the Ethereum contract. The trust documentation gives the trustee powers and duties connected to legal compliance, blockchain selection after a hard fork, and the administration of redemption. Etherscan’s proxy presentation adds a software-governance dependency because the implementation can be upgraded through the contract’s authorized mechanism. This model may support compliance and coordinated intervention, but it also means users depend on identifiable institutions and their procedures rather than on permissionless governance.
What the structure protects, and what it does not
The trust arrangement is intended to separate the trust assets from the trustee’s corporate assets, and the issuer says holders should generally be able to receive redemption from the trust assets even if the trustee fails. That is not equivalent to deposit insurance, a government guarantee, or a promise that every secondary-market price will remain exactly one yen. JPYSC is not legal tender, is not a bank deposit, and is not covered by Japan’s deposit-insurance system. Redemption can also be delayed by transaction monitoring, anti-money-laundering procedures, system failures, blockchain disruptions, or other legal and operational constraints.
Key takeaways
- JPYSC is a trust-based Japanese yen electronic payment instrument issued by SBI Shinsei Trust Bank.
- The reserve structure uses bank deposits and Japanese government bonds, with assets held separately from the trustee’s own property.
- SBI VC Trade is the main customer access point for purchase and buyback, while direct redemption from the trustee is also described.
- An Ethereum contract exists, but SBI VC Trade currently does not support JPYSC deposits or withdrawals.
- The contract is presented as an upgradeable proxy, creating a continuing software-control dependency.
- The design targets regulated settlement and tokenized-asset use cases, but several broader applications remain prospective.
Risks and open questions
- The issuer discloses that Japanese government bond valuations could contribute to a shortfall against JPYSC principal, despite the trust-asset structure.
- Public-chain transfers are not currently enabled through SBI VC Trade, limiting practical interoperability and external liquidity.
- Redemption depends on identity checks, transaction monitoring, banking procedures, and the operational continuity of SBI VC Trade and SBI Shinsei Trust Bank.
- The Ethereum deployment is upgradeable, and the available evidence does not establish the full scope of upgrade-admin controls or change-approval procedures.
- JPYSC is not legal tender, a bank deposit, or deposit-insurance-protected money.
- The official issuer page reports approximately 10.008 billion yen of issued trust beneficiary rights as of June 30, 2026, which differs materially from the larger supply figure in the local market profile and should be reconciled before using supply data.
YearBull Rank on this page
Most recent YearBull Rank reading for jpysc is #80047.
Rank change (reference points).
Reading rule: lower numbers mean higher placement.
- 7d window (2026-09-19): #3023 → #80047 (down by 77024).
